A quarter of a mile beyond this river a creek falls in on the south, to which on account of its distance from the mouth of the Missouri, we gave it the name of Two-thousand mile creek: it is a bold stream with a bed thirty yards wide. Three miles and a half above Porcupine river, we reached some high timber on the north, and encamped just above an old channel of the river, which is now dry. We saw vast quantities of buffaloe, elk, deer, principally of the long tailed kind, antelopes, beaver, geese, ducks, brant, and some swan. The porcupines too are numerous, and so careless and clumsy that we can approach very near without disturbing them as they are feeding on the young willows; towards evening we also found for the first time, the nest of a goose among some driftwood, all that we have hitherto seen being on the top of a broken tree on the forks, and invariably from fifteen to twenty feet or more in height.

Saturday 4. We were detained till nine in order to repair the rudder of one of the boats, and when we set out the wind was ahead; at six and a half miles we passed a small creek in a deep bend on the south with a sand island opposite to it, and then passing along an extensive plain which gradually rises from the north side of the river, encamped at the distance of eighteen miles in a point of woodland on the north: the river is this day wider than usual, and crowded with sandbars on all sides: the country is level, fertile, and beautiful, the low grounds extensive and contain a much greater portion of timber than is common: indeed all the forepart of the day the river was bordered with timber on both sides, a circumstance very rare on the Missouri, and the first that has occurred since we left the Mandans. There are as usual vast quantities of game, and extremely gentle; the male buffaloe particularly will scarcely give way to us, and as we approach will merely look at us for a moment, as something new, and then quietly resume their feeding. In the course of the day we passed some old Indian hunting camps, one of which consisted of two large lodges fortified with a circular fence, twenty or thirty feet in diameter, and made of timber laid horizontally, the beams overlaying each other to the height of five feet, and covered with the trunks and limbs of trees that have drifted down the river: the lodges themselves are formed by three or more strong sticks about the size of a man's leg or arm, and twelve feet long, which are attached at the top by a whith of small willows, and spreading out so as to form at the base a circle of ten or fourteen feet in diameter: against these are placed pieces of driftwood and fallen timber, usually in three ranges one on the other, and the interstices are covered with leaves, bark, and straw, so as to form a conical figure about ten feet high, with a small aperture in one side for the door. It is, however, at best a very imperfect shelter against the inclemencies of the seasons.

Sunday 5. We had a fine morning, and the wind being from the east we used our sails. At the distance of five miles we came to a small island, and twelve miles farther encamped on the north, at the distance of seventeen miles. The country like that of yesterday is beautiful in the extreme. Among the vast quantities of game around us, we distinguish a small species of goose differing considerably from the common Canadian goose; its neck, head, and beak, being much thicker, larger, and shorter in proportion to its size, which is nearly a third smaller; the noise too resembling more that of the brant or of a young goose that has not yet fully acquired its note; in other respects its colour, habits, and the number of feathers in the tail, the two species correspond; this species also associates in flocks with the large geese, but we have not seen it pair off with them. The white brant is about the size of the common brown brant, or two thirds of the common goose, than which it is also six inches shorter from the extremity of the wings, though the beak, head, and neck are larger and stronger: the body and wings are of a beautiful pure white, except the black feathers of the first and second joints of the wings; the beak and legs are of a reddish or flesh-coloured white, the eye of a moderate size, the pupil of a deep sea-green incircled with a ring of yellowish brown, the tail consists of sixteen feathers equally long, the flesh is dark and as well as its note differs but little from those of the common brant, whom in form and habits it resembles, and with whom it sometimes unites in a common flock; the white brant also associate by themselves in large flocks, but as they do not seem to be mated or paired off, it is doubtful whether they reside here during the summer for the purpose of rearing their young.

The wolves are also very abundant, and are of two species. First, the small wolf or burrowing dog of the prairies, which are found in almost all the open plains. It is of an intermediate size between the fox and dog, very delicately formed, fleet and active. The ears are large, erect, and pointed, the head long and pointed, like that of the fox; the tail long and bushy; the hair and fur of a pale reddish brown colour, though much coarser than that of the fox; the eye of a deep sea-green colour, small and piercing; the talons rather longer than those of the wolf of the Atlantic states, which animal as far as we can perceive is not to be found on this side of the river Platte. These wolves usually associate in bands of ten or twelve, and are rarely if ever seen alone, not being able singly to attack a deer or antelope. They live and rear their young in burrows, which they fix near some pass or spot much frequented by game, and sally out in a body against any animal which they think they can overpower, but on the slightest alarm retreat to their burrows making a noise exactly like that of a small dog.

The second species is lower, shorter in the legs and thicker than the Atlantic wolf; their colour, which is not affected by the seasons, is of every variety of shade, from a gray or blackish brown to a cream coloured white. They do not burrow, nor do they bark, but howl, and they frequent the woods and plains, and skulk along the skirts of the buffaloe herds, in order to attack the weary or wounded.

Captain Clarke and one of the hunters met this evening the largest brown bear we have seen. As they fired he did not attempt to attack, but fled with a most tremendous roar, and such was its extraordinary tenacity of life, that although he had five balls passed through his lungs and five other wounds, he swam more than half across the river to a sandbar, and survived twenty minutes. He weighed between five and six hundred pounds at least, and measured eight feet seven inches and a half from the nose to the extremity of the hind feet, five feet ten inches and half round the breast, three feet eleven inches round the neck, one foot eleven inches round the middle of the foreleg, and his talons, five on each foot, were four inches and three eighths in length. It differs from the common black bear in having its talons much longer and more blunt; its tail shorter; its hair of a reddish or bay brown, longer, finer, and more abundant; his liver, lungs, and heart, much larger even in proportion to his size, the heart particularly being equal to that of a large ox; his maw ten times larger; his testicles pendant from the belly and in separate pouches four inches apart: besides fish and flesh he feeds on roots, and every kind of wild fruit.

The antelope are now lean and with young, so that they may readily be caught at this season, as they cross the river from S.W. to N.E.

Monday 6. The morning being fair and the wind favourable, we set sail, and proceeded on very well the greater part of the day. The country continues level, rich, and beautiful; the low grounds wide and comparatively with the other parts of the Missouri, well supplied with wood. The appearances of coal, pumicestone, and burnt earth have ceased, though the salts of tartar or vegetable salts continue on the banks and sandbars, and sometimes in the little ravines at the base of the low hills. We passed three streams on the south; the first at the distance of one mile and a half from our camp was about twenty-five yards wide, but although it contained some water in standing pools it discharges none; this we called Littledry creek, about eight miles beyond which is Bigdry creek; fifty yards wide, without any water; the third is six miles further, and has the bed of a large river two hundred yards wide, yet without a drop of water: like the other two this stream, which we called Bigdry river, continues its width undiminished as far as we can discern. The banks are low, this channel formed of a fine brown sand, intermixed with a small proportion of little pebbles of various colours, and the country around flat and without trees. They had recently discharged their waters, and from their appearance and the nature of the country through which they pass, we concluded that they rose in the Black mountains, or in the level low plains which are probably between this place and the mountains; that the country being nearly of the same kind and of the same latitude, the rains of spring melting the snows about the same time, conspire with them to throw at once vast quantities of water down these channels, which are then left dry during the summer, autumn, and winter, when there is very little rain. We had to-day a slight sprinkling. But it lasted a very short time. The game is in such plenty that it has become a mere amusement to supply the party with provisions. We made twenty-five miles to a clump of trees on the north where we passed the night.

Tuesday 7. The morning was pleasant and we proceeded at an early hour. There is much driftwood floating, and what is contrary to our expectation, although the river is rising, the water is somewhat clearer than usual. At eleven o'clock the wind became so high that one of the boats was nearly sunk, and we were obliged to stop till one, when we proceeded on, and encamped on the south, above a large sandbar projecting from the north, having made fifteen miles. On the north side of the river are the most beautiful plains we have yet seen: they rise gradually from the low grounds on the water to the height of fifty or sixty feet, and then extend in an unbroken level as far as the eye can reach: the hills on the south are more broken and higher, though at some distance back the country becomes level and fertile. There are no more appearances of burnt earth, coal, or pumicestone, though that of salt still continues, and the vegetation seems to have advanced but little since the twenty-eighth of last month: the game is as abundant as usual. The bald-eagles, of whom we see great numbers, probably feed on the carcases of dead animals, for on the whole Missouri we have seen neither the blue-crested fisher, nor the fishing-hawks, to supply them with their favourite food, and the water of the river is so turbid that no bird which feeds exclusively on fish can procure a subsistence.

Wednesday 8. A light breeze from the east carried us sixteen miles, till we halted for dinner at the entrance of a river on the north. Captain Clarke who had walked on the south, on ascending a high point opposite to its entrance discovered a level and beautiful country which it watered; that its course for twelve or fifteen miles was N.W. when it divided into two nearly equal branches, one pursuing a direction nearly north, the other to the W. of N.W: its width at the entrance is one hundred and fifty yards, and on going three miles up, captain Lewis found it to be of the same breadth, and sometimes more; it is deep, gentle, and has a large quantity of water; its bed is principally of mud, the banks abrupt, about twelve feet in height, and formed of a dark, rich loam and blue clay; the low grounds near it are wide and fertile, and possess a considerable proportion of cottonwood and willow. It seems to be navigable for boats and canoes, and this circumstance joined to its course and the quantity of water, which indicates that it passes through a large extent of country, we are led to presume that it may approach the Saskashawan and afford a communication with that river. The water has a peculiar whiteness, such as might be produced by a tablespoon full of milk in a dish of tea, and this circumstance induced us to call it Milk river. In the evening we had made twenty-seven miles, and encamped on the south. The country on that side consists in general of high broken hills, with much gray, black and brown granite scattered over the surface of the ground. At a little distance from the river there is no timber on either side, the wood being confined as below to the margin of the river; so that unless the contrary is particularly mentioned, it is always understood that the upland is perfectly naked, and that we consider the low grounds well timbered if even a fifth be covered with wood. The wild liquorice is found in great abundance on these hills, as is also the white apple. As usual we are surrounded by buffaloe, elk, common and blacktailed deer, beaver, antelopes and wolves. We observed a place where an Indian had recently taken the hair off an antelope's skin, and some of the party thought they distinguished imperfectly some smoke and Indian lodges up Milk river, marks which we are by no means desirous of realizing, as the Indians are probably Assiniboins, and might be very troublesome.

Thursday, 9th. We again had a favourable wind and sailed along very well. Between four and five miles we passed a large island in a deep bend to the north, and a large sandbar at the upper point. At fifteen and a quarter miles we reached the bed of a most extraordinary river which presents itself on the south: though as wide as the Missouri itself, that is about half a mile, it does not discharge a drop of water and contains nothing but a few standing pools. On ascending it three miles we found an eminence from which we saw the direction of the channel, first south for ten or twelve miles, then turning to the east of southeast as far as we could see; it passes through a wide valley without timber, and the surrounding country consists of waving low hills interspersed with some handsome level plains; the banks are abrupt and consist of a black or yellow clay; or of a rich sandy loam, but though they do not rise more than six or eight feet above the bed, they exhibit no appearance of being overflowed: the bed is entirely composed of a light brown sand, the particles of which like those of the Missouri are extremely fine. Like the dry rivers we passed before, this seemed to have discharged its waters recently, but the watermark indicated that its greatest depth had not been more than two feet: this stream, if it deserve the name, we called Bigdry river. About a mile below is a large creek on the same side, which is also perfectly dry: the mineral salts and quartz are in large quantities near this neighbourhood. The sand of the Missouri from its mouth to this place has been mixed with a substance which we had presumed to be a granulated chalk, but which is most probably this quartz. The game is now in great quantities, particularly the elk and buffaloe, which last is so gentle that the men are obliged to drive them out of the way with sticks and stones. The ravages of the beaver are very apparent: in one place the timber was entirely prostrated for a space of three acres in front on the river and one in depth, and great part of it removed, although the trees were in large quantities, and some of them as thick as the body of a man. At the distance of twenty-four miles we encamped, after making twenty-five and a half miles, at the entrance of a small creek in a bend on the north; to which we gave the name of Werner's creek after one of our men.

For several days past the river has been as wide as it generally is near its mouth, but as it is much shallower, crowded with sandbars, and the colour of the water has become much clearer, we do not yet despair of reaching the Rock mountains, for which we are very anxious.

Friday, 10th. We had not proceeded more than four and a quarter miles when the violence of the wind forced us to halt for the day under some timber in a bend on the south side. The wind continued high, the clouds thick and black, and we had a slight sprinkling of rain several times in the course of the day. Shortly after our landing a dog came to us, and as this induced us to believe that we are near the hunting grounds of the Assiniboins, who are a vicious ill-disposed people, it was necessary to be on our guard: we therefore inspected our arms which we found in good order, and sent several hunters to scour the country, but they returned in the evening having seen no tents, nor any recent tracks of Indians. Biles and imposthumes are very common among the party, and sore eyes continue in a greater or less degree with all of us; for the imposthumes we use emollient poultices, and apply to the eyes a solution of two grains of white vitriol and one of sugar of lead with one ounce of water.

Saturday, 11th. The wind blew very hard in the night, but having abated this morning we went on very well, till in the afternoon the wind arose and retarded our progress; the current too was strong, the river very crooked, and the banks as usual constantly precipitating themselves in large masses into the water. The highlands are broken and approach nearer the river than they do below. The soil however of both hills and low grounds appear as fertile as that further down the river: it consists of a black looking loam with a small portion of sand, which cover the hills and bluffs to the depth of twenty or thirty feet, and when thrown in the water dissolves as readily as loaf-sugar, and effervesces like marle; there are also great appearances of quartz and mineral salts: the first is most commonly seen in the faces of the bluffs, the second is found on the hills as well as the low grounds, and in the gullies which come down from the hills; it lies in a crust of two or three inches in depth, and may be swept up with a feather in large quantities. There is no longer any appearance of coal burnt earth or pumicestone. We saw and visited some high hills on the north side about three miles from the river, whose tops were covered with the pitch-pine: this in the first pine we have seen on the Missouri, and it is like that of Virginia, except that the leaves are somewhat longer; among this pine is also a dwarf cedar, sometimes between three or four feet high, but generally spreading itself like a vine along the surface of the earth, which it covers very closely, putting out roots from the under side. The fruit and smell resemble those of the common red cedar, but the leaf is finer and more delicate. The tops of the hills where these plants grow have a soil quite different from that just described, the basis of it is usually yellow or white clay, and the general appearance light coloured, sandy, and barren, some scattering tufts of sedge being almost its only herbage. About five in the afternoon one of our men who had been afflicted with biles, and suffered to walk on shore, came running to the boats with loud cries and every symptom of terror and distress: for some time after we had taken him on board he was so much out of breath as to be unable to describe the cause of his anxiety, but he at length told us that about a mile and a half below he had shot a brown bear which immediately turned and was in close pursuit of him; but the bear being badly wounded could not overtake him. Captain Lewis with seven men immediately went in search of him, and having found his track followed him by the blood for a mile, and found him concealed in some thick brushwood, and shot him with two balls through the skull. Though somewhat smaller than that killed a few days ago, he was a monstrous animal and a most terrible enemy: our man had shot him through the centre of the lungs, yet he had pursued him furiously for half a mile, then returned more than twice that distance, and with his talons had prepared himself a bed in the earth two feet deep and five feet long, and was perfectly alive when they found him, which was at least two hours after he received the wound. The wonderful power of life which these animals possess render them dreadful: their very track in the mud or sand, which we have sometimes found eleven inches long and seven and a quarter wide, exclusive of the talons, is alarming; and we had rather encounter two Indians than meet a single brown bear. There is no chance of killing them by a single shot unless the ball goes through the brains, and this is very difficult on account of two large muscles which cover the side of the forehead, and the sharp projection of the centre of the frontal bone, which is also thick. Our encampment was on the south at the distance of sixteen miles from that of last night; the fleece and skin of the bear were a heavy burden for two men, and the oil amounted to eight gallons.

Sunday, 12th. The weather being clear and calm, we set out early. Within a mile we came to a small creek, about twenty yards wide, emptying itself on the south. At eleven and three quarter miles we reached a point of woodland on the south, opposite to which is a creek of the same width as the last, but with little water, which we called Pine creek. At eighteen and three quarter miles we came to on the south opposite to the lower point of a willow island, situated in a deep bend of the river to the southeast: here we remained during the day, the wind having risen at twelve so high that we could not proceed: it continued to blow violently all night, with occasional sprinklings of rain from sunset till midnight. On both sides of the river the country is rough and broken, the low grounds becoming narrower; the tops of the hills on the north exhibits some scattered pine and cedar, on the south the pine has not yet commenced, though there is some cedar on the sides of the hills and in the little ravines. The chokecherry, the wild hysop, sage, fleshy-leafed thorn, and particularly the aromatic herb on which the antelope and hare feed, are to be found on the plains and hills. The soil of the hills has now altered its texture considerably: their bases, like that of the river plains, is as usual a rich, black loam, while from the middle to the summits they are composed of a light brown-coloured earth, poor and sterile, and intermixed with a coarse white sand.

Monday, 13th. The wind was so strong that we could not proceed till about one o'clock, when we had to encounter a current rather stronger than usual. In the course of a mile and a half we passed two small creeks on the south, one of eighteen the other of thirty yards width, but neither of them containing any water, and encamped on the south at a point of woodland, having made only seven miles. The country is much the same as yesterday, with little timber in the low grounds, and a small quantity of pine and cedar on the northern hills. The river however continues to grow clearer, and this as well as the increased rapidity induces us to hope for some change of country. The game is as usual so abundant that we can get without difficulty all that is necessary.

Tuesday, 14th. There was some fog on the river this morning, which is a very rare occurrence. At the distance of a mile and a half we reached an island in a bend on the north, which continued for about half a mile, when at the head of it a large creek comes in on the north, to which we gave the name of Gibson's creek. At seven and a half miles is a point of rocks on the south, above a creek on the same side, which we called Sticklodge creek: five miles further is a large creek on the south, which like the two others has no running water; and at sixteen and a half miles a timbered point on the north, where we encamped for the night. The country is like that of yesterday, except that the low grounds are wider; there are also many high black bluffs along the banks: the game too is in great abundance. Towards evening the men in the hindmost canoes discovered a large brown bear lying in the open grounds, about three hundred paces from the river: six of them, all good hunters, immediately went to attack him, and concealing themselves by a small eminence came unperceived within forty paces of him: four of the hunters now fired, and each lodged a ball in his body, two of them directly through the lungs: the furious animal sprung up and ran openmouthed upon them; as he came near, the two hunters who had reserved their fire gave him two wounds, one of which breaking his shoulder retarded his motion for a moment; but before they could reload he was so near that they were obliged to run to the river, and before they reached it he had almost overtaken them: two jumped into the canoe; the other four separated, and concealing themselves in the willows fired as fast as each could reload: they struck him several times, but instead of weakening the monster each shot seemed only to direct him towards the hunter, till at last he pursued two of them so closely, that they threw aside their guns and pouches, and jumped down a perpendicular bank of twenty feet into the river; the bear sprang after them, and was within a few feet of the hindmost, when one of the hunters on shore shot him in the head and finally killed him: they dragged him to the shore, and found that eight balls had passed through him in different directions; the bear was old and the meat tough, so that they took the skin only, and rejoined us at camp, where we had been as much terrified by an accident of a different kind. This was the narrow escape of one of our canoes containing all our papers, instruments, medicine, and almost every article indispensible for the success of our enterprise. The canoe being under sail, a sudden squall of wind struck her obliquely, and turned her considerably. The man at the helm, who was unluckily the worst steersman of the party, became alarmed, and instead of putting her before the wind luffed her up into it. The wind was so high that it forced the brace of the squaresail out of the hand of the man who was attending it, and instantly upset the canoe, which would have turned bottom upwards but for the resistance made by the awning. Such was the confusion on board, and the waves ran so high, that it was half a minute before she righted, and then nearly full of water, but by baling out she was kept from sinking until they rowed ashore; besides the loss of the lives of three men who not being able to swim would probably have perished, we should have been deprived of nearly every thing necessary for our purpose, at a distance of between two and three thousand miles from any place where we could supply the deficiency.

Wednesday 15. As soon as a slight shower of rain had passed, we spread out the articles to dry; but the weather was so damp and cloudy that they derived little benefit from exposure. Our hunters procured us deer, buffaloe, and beaver.

Thursday 16. The morning was fair and we were enabled to dry and repack our stores: the loss we sustained is chiefly in the medicines, many articles of which are completely spoiled, and others considerably injured. At four o'clock we embarked, and after making seven miles encamped on the north near some wood: the country on both sides is broken, the low grounds narrower and with less timber, though there are some scattered pine and cedar on the steep declivities of the hills, which are now higher than usual. A white bear tore the coat of one of the men which he had left on shore; and two of the party wounded a large panther who was feasting on a deer. We caught some lean antelopes as they were swimming the river, and killed two buffaloe.

Friday 17. We set out early and proceeded on very well; the banks being firm and the shore bold we were enabled to use the towline, which, whenever the banks will permit it, is the safest and most expeditious mode of ascending the river, except under a sail with a steady breeze. At the distance of ten and a half miles we came to the mouth of a small creek on the south, below which the hills approach the river, and continue near it during the day: three miles further is a large creek on the north, and again six and three quarter miles beyond it, another large creek to the south, which contain a small quantity of running water of a brackish taste. The last we called Rattlesnake creek from our seeing that animal near it. Although no timber can be observed on it from the Missouri, it throws out large quantities of driftwood, among which were some pieces of coal brought down by the stream. We continued on one mile and a quarter, and encamped on the south, after making twenty and a half miles. The country in general is rugged, the hills high, with their summits and sides partially covered with pine and cedar, and their bases on both sides washed by the river: like those already mentioned the lower part of these hills is a dark rich loam, while the upper region for one hundred and fifty feet consists of a whitish brown sand, so hard as in many places to resemble stone, though in fact very little stone or rock of any kind is to be seen on the hills. The bed of the Missouri is much narrower than usual, being not more than between two and three hundred yards in width, with an uncommonly large proportion of gravel; but the sandbars, and low points covered with willows have almost entirely disappeared: the timber on the river consists of scarcely any thing more than a few scattered cottonwood trees. The saline incrustations along the banks and the foot of the hills are more abundant than usual. The game is in great quantities, but the buffaloe are not so numerous as they were some days ago: two rattlesnakes were seen to-day, and one of them killed: it resembles those of the middle Atlantic states, being about two feet six inches long, of a yellowish brown on the back and sides, variegated with a row of oval dark brown spots lying transversely on the back from the neck to the tail, and two other rows of circular spots of the same colour on the sides along the edge of the scuta: there are one hundred and seventy-six scuta on the belly, and seventeen on the tail. Captain Clarke saw in his excursions a fortified Indian camp which appeared to have been recently occupied, and was, we presumed, made by a party of Minnetarees who went to war last March.

Late at night we were roused by the sergeant of the guard in consequence of a fire which had communicated to a tree overhanging our camp. The wind was so high, that we had not removed the camp more than a few minutes when a large part of the tree fell precisely on the spot it had occupied, and would have crushed us if we had not been alarmed in time.

Saturday 18. The wind continued high from the west, but by means of the towline we were able to make nineteen miles, the sandbars being now few in number, the river narrow and the current gentle; the willow has in a great measure disappeared, and even the cottonwood, almost the only timber remaining, is growing scarce. At twelve and three quarter miles we came to a creek on the north, which was perfectly dry. We encamped on the south opposite the lower point of an island.

Sunday 19. The last night was disagreeably cold; and in the morning there was a very heavy fog which obscured the river so much as to prevent our seeing the way. This is the first fog of any degree of thickness which we have experienced: there was also last evening a fall of dew, the second which we have seen since entering this extensive open country. About eight o'clock the fog dispersed, and we proceeded with the aid of the towline: the island near which we were encamped, was three quarters of a mile in length. The country resembles that of yesterday, high hills closely bordering the river. In the afternoon the river became crooked, and contained more sawyers or floating timber than we have seen in the same space since leaving the Platte. Our game consisted of deer, beaver, and elk: we also killed a brown bear, who, although shot through the heart, ran at his usual pace nearly a quarter of a mile before he fell. At twenty-one miles is a willow island half a mile in length, on the north side, a quarter of a mile beyond which is a shoal of rapid water under a bluff: the water continued very strong for some distance beyond it: at half a mile we came to a sandbar on the north, from which to our place of encampment was another half mile, making in all twenty-two and a quarter miles. The saline substances which we have mentioned continue to appear; and the men are much afflicted with sore eyes and imposthumes.

Monday 20. As usual we set out early, and the banks being convenient for that purpose, we used the towline: the river is narrow and crooked, the water rapid, and the country much like that of yesterday: at the distance of two and a quarter miles we passed a large creek with but little water, to which we gave the name of Blowingfly creek, from the quantity of those insects found in its neighbourhood. They are extremely troublesome, infesting our meat whilst cooking and at our meals. After making seven miles we reached by eleven o'clock the mouth of a large river on the south, and encamped for the day at the upper point of its junction with the Missouri. This stream which we suppose to be that called by the Minnetarees the Muscleshell river, empties into the Missouri two thousand two hundred and seventy miles above the mouth of the latter river, and in latitude 47 degrees 0' 24" 6 north. It is one hundred and ten yards wide, and contains more water than streams of that size usually do in this country; its current is by no means rapid, and there is every appearance of its being susceptible of navigation by canoes for a considerable distance: its bed is chiefly formed of coarse sand and gravel, with an occasional mixture of black mud; the banks abrupt and nearly twelve feet high, so that they are secure from being overflowed: the water is of a greenish yellow cast and much more transparent than that of the Missouri, which itself, though clearer than below, still retains its whitish hue and a portion of its sediment. Opposite to the point of junction the current of the Missouri is gentle, and two hundred and twenty-two yards in width, the bed principally of mud (the little sand remaining being wholly confined to the points) and still too deep to use the setting pole. If this be, as we suppose, the Muscleshell, our Indian information is, that it rises in the first chain of the Rocky mountains not far from the sources of the Yellowstone, whence in its course to this place it waters a high broken country, well timbered particularly on its borders, and interspersed with handsome fertile plains and meadows. We have reason, however, to believe, from their giving a similar account of the timber where we now are, that the timber of which they speak is similar to that which we have seen for a few days past, which consists of nothing more than a few straggling small pine and dwarf cedar, on the summits of the hills, nine-tenths of the ground being totally destitute of wood, and covered with a short grass, aromatic herbs, and an immense quantity of prickly pears: though the party who explored it for eight miles represented low grounds on the river as well supplied with cottonwood of a tolerable size, and of an excellent soil. They also reported that the country is broken and irregular like that near our camp; that about five miles up a handsome river about fifty yards wide, which we named after Chaboneau's wife, Sahcajahweah, or Birdwoman's river, discharges itself into the Muscleshell on the north or upper side. Another party found at the foot of the southern hills, about four miles from the Missouri, a fine bold spring, which in this country is so rare that since we left the Mandans we have found only one of a similar kind, and that was under the bluffs on the south side of the Missouri, at some distance from it, and about five miles below the Yellowstone: with this exception all the small fountains of which we have met a number are impregnated with the salts which are so abundant here, and with which the Missouri is itself most probably tainted, though to us who have been so much accustomed to it, the taste is not perceptible. Among the game to-day we observed two large owls, with remarkably long feathers resembling ears on the sides of the head, which we presume are the hooting owls, though they are larger and their colours are brighter than those common in the United States.

Tuesday 21. The morning being very fine we were able to employ the rope and made twenty miles to our camp on the north. The shores of the river are abrupt, bold and composed of a black and yellow clay, the bars being formed of black mud, and a small proportion of fine sand; the current strong. In its course the Missouri makes a sudden and extensive bend towards the south, to receive the waters of the Muscleshell. The neck of land thus formed, though itself high is lower than the surrounding country, and makes a waving valley extending for a great distance to the northward, with a fertile soil which, though without wood, produces a fine turf of low grass, some herbs and vast quantities of prickly pear. The country on the south is high, broken, and crowned with some pine and dwarf cedar; the leaf of this pine is longer than that of the common pitch or red pine of Virginia, the cone is longer and narrower, the imbrications wider and thicker, and the whole frequently covered with rosin. During the whole day the bends of the river are short and sudden; and the points covered with some cottonwood, large or broad leaved willow, and a small quantity of redwood; the undergrowth consisting of wild roses, and the bushes of the small honeysuckle.

The mineral appearances on the river are as usual. We do not find the grouse or prairie hen so abundant as below, and think it probable that they retire from the river to the plains during this season.

The wind had been moderate during the fore part of the day, but continued to rise towards evening, and about dark veered to northeast, and blew a storm all night. We had encamped on a bar on the north, opposite the lower point of an island, which from this circumstance we called Windy island; but we were so annoyed by clouds of dust and sand that we could neither eat nor sleep, and were forced to remove our camp at eight o'clock to the foot of an adjoining hill, which shielded us in some degree from the wind: we procured elk, deer, and buffaloe.

Wednesday 22. The wind blew so violently that it was deemed prudent to wait till it had abated, so that we did not leave the camp till ten o'clock, when we proceeded principally by the towline. We passed Windy island which is about three quarters of a mile in length: and five and a half miles above it a large island in a bend to the north: three miles beyond this we came to the entrance of a creek twenty yards wide, though with little water, which we called Grouse creek, from observing near its mouth a quantity of the prairie hen with pointed tails, the first we have seen in such numbers for several days: the low grounds are somewhat wider than usual and apparently fertile, though the short and scanty grass on the hills does not indicate much richness of soil. The country around is not so broken as that of yesterday, but is still waving, the southern hills possessing more pine than usual, and some appearing on the northern hills, which are accompanied by the usual salt and mineral appearances.

The river continues about two hundred and fifty yards wide, with fewer sandbars, and the current more gentle and regular. Game is no longer in such abundance, since leaving the Muscleshell. We have caught very few fish on this side of the Mandans, and these were the white catfish of two to five pounds. We killed a deer and a bear: we have not seen in this quarter the black bear, common in the United States and on the lower parts of the Missouri, nor have we discerned any of their tracks, which may easily be distinguished by the shortness of its talons from the brown, grizzly, or white bear, all of which seem to be of the same family, which assumes those colours at different seasons of the year. We halted earlier than usual, and encamped on the north, in a point of woods, at the distance of sixteen and a half miles.



CHAPTER IX.

The party continue their route—description of Judith river—Indian mode of taking the buffaloe—Slaughter river described—phenomena of nature—of walls on the banks of the Missouri—the party encamp on the banks of the river to ascertain which of the streams constitute the Missouri—captain Lewis leaves the party to explore the northern fork, and captain Clarke explores the southern—the surrounding country described in the route of captain Lewis—narrow escape of one of his party.

Thursday 23. Last night the frost was severe, and this morning the ice appeared along the edges of the river, and the water froze on our oars. At the distance of a mile we passed the entrance of a creek on the north, which we named Teapot creek; it is fifteen yards wide, and although it has running water at a small distance from its mouth, yet it discharges none into the Missouri, resembling, we believe, most of the creeks in this hilly country, the waters of which are absorbed by the thirsty soil near the river. They indeed afford but little water in any part, and even that is so strongly tainted with salts that it is unfit for use, though all the wild animals are very fond of it. On experiment it was found to be moderately purgative, but painful to the intestines in its operation. This creek seems to come from a range of low hills, which run from east to west for seventy miles, and have their eastern extremity thirty miles to the north of Teapot creek. Just above its entrance is a large assemblage of the burrowing squirrels on the north side of the river. At nine miles we reached the upper point of an island in a bend on the south, and opposite the centre of the island, a small dry creek on the north. Half a mile further a small creek falls in on the same side; and six and a half miles beyond this another on the south. At four and a half we passed a small island in a deep bend to the north, and on the same side in a deep northeastern bend of the river another small island. None of these creeks however possessed any water, and at the entrances of the islands, the two first are covered with tall cottonwood timber, and the last with willows only. The river has become more rapid, the country much the same as yesterday, except that there is rather more rocks on the face of the hills, and some small spruce pine appears among the pitch. The wild roses are very abundant and now in bloom; they differ from those of the United States only in having the leaves and the bush itself of a somewhat smaller size. We find the musquitoes troublesome, notwithstanding the coolness of the morning. The buffaloe is scarce to-day, but the elk, deer, and antelope, are very numerous. The geese begin to lose the feathers of the wings, and are unable to fly. We saw five bears, one of which we wounded, but in swimming from us across the river, he become entangled in some driftwood and sank. We formed our camp on the north opposite to a hill and a point of wood in a bend to the south, having made twenty-seven miles.

Friday 24. The water in the kettles froze one eighth of an inch during the night; the ice appears along the margin of the river, and the cottonwood trees which have lost nearly all their leaves by the frost, are putting forth other buds. We proceeded with the line principally till about nine o'clock, when a fine breeze sprung up from the S.E. and enabled us to sail very well, notwithstanding the rapidity of the current. At one mile and a half is a large creek thirty yards wide, and containing some water which it empties on the north side, over a gravelly bed, intermixed with some stone. A man who was sent up to explore the country returned in the evening, after having gone ten miles directly towards the ridge of mountains to the north, which is the source of this as well as of Teapot creek. The air of these highlands is so pure, that objects appear much nearer than they really are, so that although our man went ten miles without thinking himself by any means half way to the mountains, they do not from the river appear more than fifteen miles distant; this stream we called Northmountain creek. Two and a half miles higher is a creek on the south which is fifteen yards wide, but without any water, and to which we gave the name of Littledog creek, from a village of burrowing squirrels opposite to its entrance, that being the name given by the French watermen to those animals. Three miles from this a small creek enters on the north, five beyond which is an island a quarter of a mile in length, and two miles further a small river: this falls in on the south, is forty yards wide, and discharges a handsome stream of water; its bed rocky with gravel and sand, and the banks high: we called it Southmountain creek, as from its direction it seemed to rise in a range of mountains about fifty or sixty miles to the S.W. of its entrance. The low grounds are narrow and without timber; the country high and broken; a large portion of black rock, and brown sandy rock appears in the face of the hills, the tops of which are covered with scattered pine, spruce and dwarf cedar: the soil is generally poor, sandy near the tops of the hills, and nowhere producing much grass, the low grounds being covered with little else than the hysop, or southern wood, and the pulpy-leafed thorn. Game is more scarce, particularly beaver, of which we have seen but few for several days, and the abundance or scarcity of which seems to depend on the greater or less quantity of timber. At twenty-four and a half miles we reached a point of woodland on the south, where we observed that the trees had no leaves, and encamped for the night. The high country through which we have passed for some days, and where we now are, we suppose to be a continuation of what the French traders called the Cote Noire or Black hills. The country thus denominated consists of high broken irregular hills and short chains of mountains; sometimes one hundred and twenty miles in width, sometimes narrower, but always much higher than the country on either side. They commence about the head of the Kanzas, where they diverge; the first ridge going westward, along the northern shore of the Arkansaw; the second approaches the Rock mountains obliquely in a course a little to the W. of N.W. and after passing the Platte above its forks, and intersecting the Yellowstone near the Bigbend, crosses the Missouri at this place, and probably swell the country as far as the Saskashawan, though as they are represented much smaller here than to the south, they may not reach that river.

Saturday, 25th. Two canoes which were left behind yesterday to bring on the game, did not join us till eight o'clock this morning, when we set out with the towline, the use of which the banks permitted. The wind was, however, ahead, the current strong, particularly round the points against which it happened to set, and the gullies from the hills having brought down quantities of stone, those projected into the river, forming barriers for forty or fifty feet round, which it was very difficult to pass. At the distance of two and three quarter miles we passed a small island in a deep bend on the south, and on the same side a creek twenty yards wide, but with no running water. About a mile further is an island between two and three miles in length, separated from the northern shore by a narrow channel, in which is a sand island at the distance of half a mile from its lower extremity. To this large island we gave the name of Teapot island; two miles above which is an island a mile long, and situated on the south. At three and a half miles is another small island, and one mile beyond it a second three quarters of a mile in length, on the north side. In the middle of the river two miles above this is an island with no timber, and of the same extent as this last. The country on each side is high, broken, and rocky; the rock being either a soft brown sandstone, covered with a thin stratum of limestone, or else a hard black rugged granite, both usually in horizontal stratas, and the sandrock overlaying the other. Salts and quartz as well as some coal and pumicestone still appear: the bars of the river are composed principally of gravel; the river low grounds are narrow, and afford scarcely any timber; nor is there much pine on the hills. The buffaloe have now become scarce: we saw a polecat this evening, which was the first for several days: in the course of the day we also saw several herds of the big-horned animals among the steep cliffs on the north, and killed several of them. At the distance of eighteen miles we encamped on the south, and the next morning,

Sunday, 26th, proceeded on at an early hour by means of the towline, using our oars merely in passing the river, to take advantage of the best banks. There are now scarcely any low grounds on the river, the hills being high and in many places pressing on both sides to the verge of the water. The black rock has given place to a very soft sandstone, which seems to be washed away fast by the river, and being thrown into the river renders its navigation more difficult than it was yesterday: above this sandstone, and towards the summits of the hills, a hard freestone of a yellowish brown colour shows itself in several stratas of unequal thickness, frequently overlaid or incrusted by a thin stratum of limestone, which seems to be formed of concreted shells. At eight and a quarter miles we came to the mouth of a creek on the north, thirty yards wide, with some running water and a rocky bed: we called it Windsor creek, after one of the party. Four and three quarter miles beyond this we came to another creek in a bend to the north, which is twenty yards wide, with a handsome little stream of water: there is however no timber on either side of the river, except a few pines on the hills. Here we saw for the first time since we left the Mandans several soft shelled turtles, though this may be owing rather to the season of the year than to any scarcity of the animal. It was here that after ascending the highest summits of the hills on the north side of the river, that captain Lewis first caught a distant view of the Rock mountains, the object of all our hopes, and the reward of all our ambition. On both sides of the river and at no great distance from it, the mountains followed its course: above these, at the distance of fifty miles from us, an irregular range of mountains spread themselves from west to northwest from his position. To the north of these a few elevated points, the most remarkable of which bore north 65 degrees west, appeared above the horizon, and as the sun shone on the snows of their summits he obtained a clear and satisfactory view of those mountains which close on the Missouri the passage to the Pacific. Four and a half miles beyond this creek we came to the upper point of a small sand island. At the distance of five miles between high bluffs, we passed a very difficult rapid, reaching quite across the river, where the water is deep, the channel narrow, and gravel obstructing it on each side: we had great difficulty in ascending it, although we used both the rope and the pole, and doubled the crews: this is the most considerable rapid on the Missouri, and in fact the only place where there is a sudden descent: as we were labouring over them, a female elk with its fawn swam down through the waves, which ran very high, and obtained for the place the name of the Elk Rapids. Just above them is a small low ground of cottonwood trees, where, at twenty-two and a quarter miles we fixed our encampment, and were joined by captain Lewis, who had been on the hills during the afternoon.

The country has now become desert and barren: the appearances of coal, burnt earth, pumicestone, salts, and quartz, continue as yesterday: but there is no timber except the thinly scattered pine and spruce on the summits of the hills, or along the sides. The only animals we have observed are the elk, the bighorn, and the hare, common in this country. In the plain where we lie are two Indian cabins made of sticks, and during the last few days we have passed several others in the points of timber on the river.

Monday, 27. The wind was so high that we did not start till ten o'clock, and even then were obliged to use the line during the greater part of the day. The river has become very rapid with a very perceptible descent: its general width is about two hundred yards: the shoals too are more frequent, and the rocky points at the mouth of the gullies more troublesome to pass: great quantities of this stone lie in the river and on its banks, and seem to have fallen down as the rain washed away the clay and sand in which they were imbedded. The water is bordered by high rugged bluffs, composed of irregular but horizontal stratas of yellow and brown or black clay, brown and yellowish white sand, soft yellowish white sandstone: hard dark brown freestone; and also large round kidney formed irregular separate masses of a hard black ironstone, imbedded in the clay and sand; some coal or carbonated wood also makes its appearance in the cliffs, as do also its usual attendants the pumicestone and burnt earth. The salts and quartz are less abundant, and generally speaking the country is if possible more rugged and barren than that we passed yesterday; the only growth of the hills being a few pine, spruce, and dwarf cedar, interspersed with an occasional contrast once in the course of some miles, of several acres of level ground, which supply a scanty subsistence for a few little cottonwood trees.

Soon after setting out we passed a small untimbered island on the south: at about seven miles we reached a considerable bend which the river makes towards the southeast, and in the evening, after making twelve and a half miles, encamped on the south near two dead cottonwood trees, the only timber for fuel which we could discover in the neighbourhood.

Tuesday, 28. The weather was dark and cloudy; the air smoky, and there fell a few drops of rain. At ten o'clock we had again a slight sprinkling of rain, attended with distant thunder, which is the first we have heard since leaving the Mandans. We employed the line generally, with the addition of the pole at the ripples and rocky points, which we find more numerous and troublesome than those we passed yesterday. The water is very rapid round these points, and we are sometimes obliged to steer the canoes through the points of sharp rocks rising a few inches above the surface of the water, and so near to each other that if our ropes give way the force of the current drives the sides of the canoe against them, and must inevitably upset them or dash them to pieces. These cords are very slender, being almost all made of elkskin, and much worn and rotted by exposure to the weather: several times they gave way, but fortunately always in places where there was room for the canoe to turn without striking the rock; yet with all our precautions it was with infinite risk and labour that we passed these points. An Indian pole for building floated down the river, and was worn at one end as if dragged along the ground in travelling; several other articles were also brought down by the current, which indicate that the Indians are probably at no great distance above us, and judging from a football which resembles those used by the Minnetarees near the Mandans, we conjecture that they must be a band of the Minnetarees of fort de Prairie. The appearance of the river and the surrounding country continued as usual, till towards evening, at about fifteen miles, we reached a large creek on the north thirty-five yards wide, discharging some water, and named after one of our men Thompson's creek. Here the country assumed a totally different aspect; the hills retired on both sides from the river, which now spreads to more than three times its former size, and is filled with a number of small handsome islands covered with cottonwood. The low grounds on the river are again wide, fertile, and enriched with trees; those on the north are particularly wide, the hills being comparatively low and opening into three large vallies, which extend themselves for a considerable distance towards the north: these appearances of vegetation are delightful after the dreary hills over which we have passed, and we have now to congratulate ourselves at having escaped from the last ridges of the Black mountains. On leaving Thompson's creek we passed two small islands, and at twenty-three miles distance encamped among some timber on the north, opposite to a small creek, which we named Bull creek. The bighorn is in great quantities, and must bring forth their young at a very early season, as they are now half grown. One of the party saw a large bear also, but being at a distance from the river, and having no timber to conceal him, he would not venture to fire.

Wednesday, 29. Last night we were alarmed by a new sort of enemy. A buffaloe swam over from the opposite side and to the spot where lay one of our canoes, over which he clambered to the shore: then taking fright he ran full speed up the bank towards our fires, and passed within eighteen inches of the heads of some of the men, before the sentinel could make him change his course: still more alarmed he ran down between four fires and within a few inches of the heads of the second row of the men, and would have broken into our lodge if the barking of the dog had not stopped him. He suddenly turned to the right and was out of sight in a moment, leaving us all in confusion, every one seizing his rifle and inquiring the cause of the alarm. On learning what had happened, we had to rejoice at suffering no more injury than the damage to some guns which were in the canoe which the buffaloe crossed.

In the morning early we left our camp, and proceeded as usual by the cord. We passed an island and two sandbars, and at the distance of two and a half miles we came to a handsome river which discharges itself on the south, and which we ascended to the distance of a mile and a half: we called it Judith's river: it rises in the Rock mountains in about the same place with the Muscleshell and near the Yellowstone river. Its entrance is one hundred yards wide from one bank to the other, the water occupying about seventy-five yards, and in greater quantity than that of the Muscleshell river, and though more rapid equally navigable, there being no stones or rocks in the bed, which is composed entirely of gravel and mud with some sand: the water too is clearer than any which we have yet seen; and the low grounds, as far as we could discern, wider and more woody than those of the Missouri: along its banks we observed some box-alder intermixed with the cottonwood and the willow; the undergrowth consisting of rosebushes, honeysuckle, and a little red willow. There was a great abundance of the argalea or bighorned animals in the high country through which it passes, and a great number of the beaver in its waters: just above the entrance of it we saw the fires of one hundred and twenty-six lodges, which appeared to have been deserted about twelve or fifteen days, and on the other side of the Missouri a large encampment, apparently made by the same nation. On examining some moccasins which we found there, our Indian woman said that they did not belong to her own nation the Snake Indians, but she thought that they indicated a tribe on this side of the Rocky mountain, and to the north of the Missouri; indeed it is probable that these are the Minnetarees of fort de Prairie. At the distance of six and a half miles the hills again approach the brink of the river, and the stones and rocks washed down from them form a very bad rapid, with rocks and ripples more numerous and difficult than those we passed on the 27th and 28th; here the same scene was renewed, and we had again to struggle and labour to preserve our small craft from being lost. Near this spot are a few trees of the ash, the first we have seen for a great distance, and from which we named the place Ash Rapids. On these hills there is but little timber, but the salts, coal, and other mineral appearances continue. On the north we passed a precipice about one hundred and twenty feet high, under which lay scattered the fragments of at least one hundred carcases of buffaloes, although the water which had washed away the lower part of the hill must have carried off many of the dead. These buffaloe had been chased down the precipice in a way very common on the Missouri, and by which vast herds are destroyed in a moment. The mode of hunting is to select one of the most active and fleet young men, who is disguised by a buffaloe skin round his body; the skin of the head with the ears and horns fastened on his own head in such a way as to deceive the buffaloe: thus dressed, he fixes himself at a convenient distant between a herd of buffaloe and any of the river precipices, which sometimes extend for some miles. His companions in the meantime get in the rear and side of the herd, and at a given signal show themselves, and advance towards the buffaloe: they instantly take the alarm, and finding the hunters beside them, they run towards the disguised Indian or decoy, who leads them on at full speed toward the river, when suddenly securing himself in some crevice of the cliff which he had previously fixed on, the herd is left on the brink of the precipice: it is then in vain for the foremost to retreat or even to stop; they are pressed on by the hindmost rank, who seeing no danger but from the hunters, goad on those before them till the whole are precipitated and the shore is strewn with their dead bodies. Sometimes in this perilous seduction the Indian is himself either trodden under root by the rapid movements of the buffaloe, or missing his footing in the cliff is urged down the precipice by the falling herd. The Indians then select as much meat as they wish, and the rest is abandoned to the wolves, and create a most dreadful stench. The wolves who had been feasting on these carcases were very fat, and so gentle that one of them was killed with an esponton. Above this place we came to for dinner at the distance of seventeen miles, opposite to a bold running river of twenty yards wide, and falling in on the south. From the objects we had just passed we called this stream Slaughter river. Its low grounds are narrow, and contain scarcely any timber. Soon after landing it began to blow and rain, and as there was no prospect of getting wood for fuel farther on, we fixed our camp on the north, three quarters of a mile above Slaughter river. After the labours of the day we gave to each man a dram, and such was the effect of long abstinence from spirituous liquors, that from the small quantity of half a gill of rum, several of the men were considerably affected by it, and all very much exhilirated. Our game to-day consisted of an elk and two beaver.

Thursday, 30. The rain which commenced last evening continued with little intermission till eleven this morning, when the high wind which accompanied it having abated, we set out. More rain has now fallen than we have had since the 1st of September last, and many circumstances indicate our approach to a climate differing considerably from that of the country through which we have been passing: the air of the open country is astonishingly dry and pure. Observing that the case of our sextant, though perfectly seasoned, shrank and the joints opened, we tried several experiments, by which it appeared that a tablespoon full of water exposed in a saucer to the air would evaporate in thirty-six hours, when the mercury did not stand higher than the temperate point at the greatest heat of the day. The river, notwithstanding the rain, is much clearer than it was a few days past; but we advance with great labour and difficulty; the rapid current, the ripples and rocky points rendering the navigation more embarrassing than even that of yesterday, in addition to which the banks are now so slippery after the rain, that the men who draw the canoes can scarcely walk, and the earth and stone constantly falling down the high bluffs make it dangerous to pass under them; still however we are obliged to make use of the cord, as the wind is strong ahead, the current too rapid for oars, and too deep for the pole. In this way we passed at the distance of five and a half miles a small rivulet in a bend on the north, two miles further an island on the same side, half a mile beyond which came to a grove of trees at the entrance of a run in a bend to the south, and encamped for the night on the northern shore. The eight miles which we made to-day cost us much trouble. The air was cold and rendered more disagreeable by the rain, which fell in several slight showers in the course of the day; our cords too broke several times, but fortunately without injury to the boats. On ascending the hills near the river, one of the party found that there was snow mixed with the rain on the heights: a little back of these the country becomes perfectly level on both sides of the river. There is now no timber on the hills, and only a few scattering cottonwood, ash, box-alder, and willows, along the water. In the course of the day we passed several encampments of Indians, the most recent of which seemed to have been evacuated about five weeks since, and from the several apparent dates we supposed that they were made by a band of about one hundred lodges who were travelling slowly up the river. Although no part of the Missouri from the Minnetarees to this place exhibit signs of permanent settlements, yet none seem exempt from the transient visits of hunting parties. We know that the Minnetarees of the Missouri extend their excursions on the south side of the river, as high as the Yellowstone; and the Assiniboins visit the northern side, most probably as high as Porcupine river. All the lodges between that place and the Rocky mountains we supposed to belong to the Minnetarees of fort de Prairie, who live on the south fork of the Saskashawan.

Friday, 31. We proceeded in two periogues, leaving the canoes to bring on the meat of two buffaloes killed last evening. Soon after we set off it began to rain, and though it ceased at noon, the weather continued cloudy during the rest of the day. The obstructions of yesterday still remain and fatigue the men excessively: the banks are so slippery in some places and the mud so adhesive that they are unable to wear their moccasins; one fourth of the time they are obliged to be up to their armpits in the cold water, and sometimes walk for several yards over the sharp fragments of rocks which have fallen from the hills: all this added to the burden of dragging the heavy canoes is very painful, yet the men bear it with great patience and good humour. Once the rope of one of the periogues, the only one we had made of hemp, broke short, and the periogue swung and just touched a point of rock which almost overset her. At nine miles we came to a high wall of black rock rising from the water's edge on the south, above the cliffs of the river: this continued about a quarter of a mile, and was succeeded by a high open plain, till three miles further a second wall two hundred feet high rose on the same side. Three miles further a wall of the same kind about two hundred feet high and twelve in thickness, appeared to the north: these hills and river cliffs exhibit a most extraordinary and romantic appearance: they rise in most places nearly perpendicular from the water, to the height of between two and three hundred feet, and are formed of very white sandstone, so soft as to yield readily to the impression of water, in the upper part of which lie imbedded two or three thin horizontal stratas of white freestone insensible to the rain, and on the top is a dark rich loam, which forms a gradually ascending plain, from a mile to a mile and a half in extent, when the hills again rise abruptly to the height of about three hundred feet more. In trickling down the cliffs, the water has worn the soft sandstone into a thousand grotesque figures, among which with a little fancy may be discerned elegant ranges of freestone buildings, with columns variously sculptured, and supporting long and elegant galleries, while the parapets are adorned with statuary: on a nearer approach they represent every form of elegant ruins; columns, some with pedestals and capitals entire, others mutilated and prostrate, and some rising pyramidally over each other till they terminate in a sharp point. These are varied by niches, alcoves, and the customary appearances of desolated magnificence: the allusion is increased by the number of martins, who have built their globular nests in the niches and hover over these columns; as in our country they are accustomed to frequent large stone structures. As we advance there seems no end to the visionary enchantment which surrounds us. In the midst of this fantastic scenery are vast ranges of walls, which seem the productions of art, so regular is the workmanship: they rise perpendicularly from the river, sometimes to the height of one hundred feet, varying in thickness from one to twelve feet, being equally broad at the top as below. The stones of which they are formed are black, thick, and durable, and composed of a large portion of earth, intermixed and cemented with a small quantity of sand, and a considerable proportion of talk or quartz. These stones are almost invariably regular parallelipeds of unequal sizes in the wall, but equally deep, and laid regularly in ranges over each other like bricks, each breaking and covering the interstice of the two on which it rests: but though the perpendicular interstice be destroyed, the horizontal one extends entirely through the whole work: the stones too are proportioned to the thickness of the wall in which they are employed, being largest in the thickest walls. The thinner walls are composed of a single depth of the paralleliped, while the thicker ones consist of two or more depths: these walls pass the river at several places, rising from the water's edge much above the sandstone bluffs which they seem to penetrate; thence they cross in a straight line on either side of the river, the plains over which they tower to the height of from ten to seventy feet, until they lose themselves in the second range of hills: sometimes they run parallel in several ranges near to each other, sometimes intersect each other at right angles, and have the appearance of walls of ancient houses or gardens.

The face of some of these river hills, is composed of very excellent freestone of a light yellowish brown colour, and among the cliffs we found a species of pine which we had not yet seen, and differing from the Virginia pitchpine in having a shorter leaf, and a longer and more pointed cone. The coal appears only in small quantities, as do the burnt earth and pumicestone: the mineral salts have abated. Among the animals are a great number of the bighorn, a few buffaloe and elk, and some mule-deer, but none of the common deer nor any antelopes. We saw but could not procure a beautiful fox, of a colour varied with orange, yellow, white, and black, rather smaller than the common fox of this country, and about the same size as the red fox of the United States.

The river to-day has been from about one hundred and fifty to two hundred and fifty yards wide, with but little timber. At the distance of two miles and a half from the last stone wall, is a stream on the north side, twenty-eight yards in width, and with some running water. We encamped just above its mouth having made eighteen miles.

Saturday, June 1. The weather was cloudy with a few drops of rain. As we proceeded by the aid of our cord we found the river cliffs and bluffs not so high as yesterday, and the country more level. The timber too is in greater abundance on the river, though there is no wood on the high ground; coal however appears in the bluffs. The river is from two hundred to two hundred and fifty feet wide, the current more gentle, the water becoming still clearer and fewer rocky points and shoals than we met yesterday, though those which we did encounter were equally difficult to pass. Game is by no means in such plenty as below; all that we obtained were one bighorn, and a mule-deer though we saw in the plains a quantity of buffaloe, particularly near a small lake about eight miles from the river to the south. Notwithstanding the wind was ahead all day, we dragged the canoes along the distance of twenty-three miles. At fourteen and a quarter miles, we came to a small island opposite a bend of the river to the north: two and a half miles to the upper point of a small island on the north; five miles to another island on the south side and opposite to a bluff. In the next two miles we passed an island on the south, a second beyond it on the north, and reached near a high bluff on the north a third on which we encamped. In the plains near the river are the chokecherry, yellow and red currant-bushes, as well as the wild rose and prickly pear, both of which are now in bloom. From the tops of the river hills, which are lower than usual, we enjoyed a delightful view of the rich fertile plains on both sides, in many places extending from the river cliffs to a great distance back. In these plains we meet occasionally large banks of pure sand, which were driven apparently by the southwest winds, and there deposited. The plains are more fertile some distance from the river than near its banks, where the surface of the earth is very generally strewed with small pebbles, which appear to be smoothed and worn by the agitation of the waters with which they were no doubt once covered. A mountain or part of the North mountain approaches the river within eight or ten miles, bearing north from our encampment of last evening; and this morning a range of high mountains bearing S.W. from us and apparently running to the westward, are seen at a great distance covered with snow. In the evening we had a little more rain.

Sunday 2. The wind blew violently last night, and a slight shower of rain fell, but this morning was fair. We set out at an early hour, and although the wind was ahead by means of the cord went on much better than for the last two days, as the banks were well calculated for towing. The current of the river is strong but regular, its timber increases in quantity, the low grounds become more level and extensive, and the bluffs on the river are lower than usual. In the course of the day we had a small shower of rain, which lasted a few minutes only. As the game is very abundant we think it necessary to begin a collection of hides for the purpose of making a leathern boat, which we intend constructing shortly. The hunters who were out the greater part of the day brought in six elk, two buffaloe, two mule-deer and a bear. This last animal had nearly cost us the lives of two of our hunters who were together when he attacked them: one of them narrowly escaped being caught, and the other after running a considerable distance, concealed himself in some thick bushes, and while the bear was in quick pursuit of his hiding place, his companion came up and fortunately shot the animal through the head.

At six and at half miles we reached an island on the northern side; one mile and a quarter thence is a timbered low ground on the south: and in the next two and three quarter miles we passed three small islands, and came to a dark bluff on the south: within the following mile are two small islands on the same side. At three and a quarter miles we reached the lower part of a much larger island near a northern point, and as we coasted along its side, within two miles passed a smaller island, and half a mile above reached the head of another. All these islands are small, and most of them contain some timber. Three quarters of a mile beyond the last, and at the distance of eighteen miles from our encampment, we came to for the night in a handsome low cottonwood plain on the south, where we remained for the purpose of making some celestial observations during the night, and of examining in the morning a large river which comes in opposite to us. Accordingly at an early hour,

Monday, 3d, we crossed and fixed our camp in the point, formed by the junction of the river with the Missouri. It now became an interesting question which of these two streams is what the Minnetarees call Ahmateahza or the Missouri, which they described as approaching very near to the Columbia. On our right decision much of the fate of the expedition depends; since if after ascending to the Rocky mountains or beyond them, we should find that the river we were following did not come near the Columbia, and be obliged to return; we should not only lose the travelling season, two months of which had already elapsed, but probably dishearten the men so much as to induce them either to abandon the enterprise, or yield us a cold obedience instead of the warm and zealous support which they had hitherto afforded us. We determined, therefore, to examine well before we decided on our future course; and for this purpose despatched two canoes with three men up each of the streams with orders to ascertain the width, depth, and rapidity of the current, so as to judge of their comparative bodies of water. At the same time parties were sent out by land to penetrate the country, and discover from the rising grounds, if possible, the distant bearings of the two rivers; and all were directed to return towards evening. While they were gone we ascended together the high grounds in the fork of these two rivers, whence we had a very extensive prospect of the surrounding country: on every side it was spread into one vast plain covered with verdure, in which innumerable herds of buffaloe were roaming, attended by their enemies the wolves: some flocks of elk also were seen, and the solitary antelopes were scattered with their young over the face of the plain. To the south was a range of lofty mountains, which we supposed to be a continuation of the South mountain, stretching themselves from southeast to northwest, and terminating abruptly about southwest from us. These were partially covered with snow; but at a great distance behind them was a more lofty ridge completely covered with snow, which seemed to follow the same direction as the first, reaching from west to the north of northwest, where their snowy tops were blended with the horizon. The direction of the rivers could not however be long distinguished, as they were soon lost in the extent of the plain. On our return we continued our examination; the width of the north branch is two hundred yards, that of the south is three hundred and seventy-two. The north, although narrower and with a gentler current, is deeper than the south: its waters too are of the same whitish brown colour, thickness, and turbidness: they run in the same boiling and rolling manner which has uniformly characterized the Missouri; and its bed is composed of some gravel, but principally mud. The south fork is deeper, but its waters are perfectly transparent: its current is rapid, but the surface smooth and unruffled; and its bed too is composed of round and flat smooth stones like those of rivers issuing from a mountainous country. The air and character of the north fork so much resemble those of the Missouri that almost all the party believe that to be the true course to be pursued. We however, although we have given no decided opinion, are inclined to think otherwise, because, although this branch does give the colour and character to the Missouri, yet these very circumstances induce an opinion that it rises in and runs through an open plain country, since if it came from the mountains it would be clearer, unless, which from the position of the country is improbable, it passed through a vast extent of low ground after leaving them: we thought it probable that it did not even penetrate the Rocky mountains, but drew it sources from the open country towards the lower and middle parts of the Saskashawan, in a direction north of this place. What embarrasses us most is, that the Indians who appeared to be well acquainted with the geography of the country, have not mentioned this northern river; for "the river which scolds at all others," as it is termed, must be according to their account one of the rivers which we have passed; and if this north fork be the Missouri, why have they not designated the south branch which they must also have passed, in order to reach the great falls which they mention on the Missouri. In the evening our parties returned, after ascending the rivers in canoes for some distance, then continuing on foot, just leaving themselves time to return by night. The north fork was less rapid, and therefore afforded the easiest navigation: the shallowest water of the north was five feet deep, that of the south six feet. At two and a half miles up the north fork is a small river coming in on the left or western side, sixty feet wide, with a bold current three feet in depth. The party by land had gone up the south fork in a straight line, somewhat north of west for seven miles, where they discovered that this little river came within one hundred yards of the south fork, and on returning down it found it a handsome stream, with as much timber as either of the larger rivers, consisting of the narrow and wide-leafed cottonwood, some birch and box-alder, amid undergrowth of willows, rosebushes, and currants: they also saw on this river a great number of elk and some beaver.
